^
exit status 1
expected unqualified-id before 'if'
this report have more information with
"show verbose output during compilation"
option enabled in file -> preferences.
here actual code
code: [select]
#include <liquidcrystal.h>
// initialize library numbers of interface pins
liquidcrystal lcd(12, 11, 5, 4, 3, 2);
void setup() {
// set lcd's number of columns , rows:
lcd.begin(16, 2);
}
if (thischar == 10)
{
lcd.clear();
}
void loop() {
// set cursor (0,0):
lcd.setcursor(0, 0);
// print 0 9:
(int thischar = 1; thischar < 112; thischar++) {
lcd.print(thischar);
delay(1000);
}
// set cursor (16,1):
lcd.setcursor(16, 1);
// set display automatically scroll:
lcd.autoscroll();
// print 0 9:
(int thischar = 1; thischar < 12; thischar++) {
lcd.print(thischar);
delay(1000);
}
// turn off automatic scrolling
lcd.noautoscroll();
// clear screen next loop:
lcd.clear();
}
eventually want make hour long timer uses buzzer beep after hour. testing
code: [select]
thischar
command code: [select]
